摘要
A modification of a colorimetric assay (1) discriminating galactosamine and glucosamine in mixtures is presented. The procedure employs acetylation of the amino sugars at 25°C instead of at 0-1°C, resulting in five times the color intensity for galactosamine with no interference due to glucosamine. The assay of HCl hydrolysates of glycosaminoglycans and glycoproteins is possible in solutions that are less than 0.1 n. © 1979.
